SPECIFICATION forming part of Letters Patent No. 455,284, dated J' une30, 1891-.

Application filed September 30,1890. Serial No. 366,650. (No model.) l

. To @ZZ whom t may concern:

Be it known that I, CHARLES D. HUFF, a citizen of the United States,residing at Dallas, in the county of Luzerne and State of Pennsylvania,have invented a new and useful Thill-Coupling, of which the following isa specification.

The invention relates thill-couplings.

The object of the present invention is to simplify and improve theconstruction of thillcouplings, increase their strength and durabilityand enable the shaft-irons to be readily separated from their pivots7and to facilitate the attachment of anti-rattler springs.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure l is a perspective view of a thill-couplingembodying the invention. Fig. 2 is a longitudinal sectional view. Fig.is a transverse sectional View.

Referring to the accompanying drawings, l designates an axle-clip of theusual construction, having depending threaded ends 2 and provided withparallel forwardly-extending ears 8, connected by a transverse rivet 4,which forms the pivot of a shaft-iron 5. The shaft-iron 5 has its eyes 6provided with a transverse opening 7, by means of which the thill-ironwhen elevated can be readily brought into engagement with and disengagedfrom the rivet 4. The threaded ends of the clip l are engaged by nuts 8,which secure the clip-plate 9 on the ends, and the said plate 9 toimprovements in 10, which is arrangedl beneath the ears and 4o forms abearing for the thill-iron 5. An antirattler spring l1 is interposedbetween the thill-iron and the clip andit'straddles the forwardextension of the clip-plate and is arranged bet-Ween the ears of theclip.

It will be seen that the thill-coupling or anti-rattler is simple andinexpensive in construction, is strong anddurable, and is capable ofenabling the shaft to be readily removed and replaced.

In a thill-coupling, the combination of the clip provided with theforwardly-extending ears vand having the rigid transverse rivetsconnecting the ears, the thill-iron having its eye provided with atransverse opening adapted to engage the transverse rivet, the clipplatehaving the straight rigid unyielding extension arranged beneath thetransverse rivet and projecting forward beyond the rivet and said eyeand having a raised convex upper face and forming a bearing or supportfor the same, and the approximately U-shaped anti-rattler springinterposed between the clip and the thill-iron and straddling theextension of the clip, substantially as described.

In testimony that I claim the foregoing as my own I' have hereto affixedmy signature in presence of two witnesses.

CHARLES D. HUFF.
